Mudskippers are actually a species of fish found in mangroves and mudflats. Spending most of their time out of the water, they’re adapted to remain on land even after the tide has gone out. They mostly breathe by holding water in their mouth and gill chamber, though staying damp also allows them to breathe through their skin. Their large eyes make them excellent predators, while their pectoral fins act as legs, allowing them to crawl over mud and trees along the mangrove floor.
